In a study looking at brain scans of people with mild loss of thought and memory ability, researchers report evidence of lower levels of the serotonin transporter — a natural brain chemical that regulates mood, sleep and appetite.

A lay person, or a person intending to mislead, would jump to the conclusion that low serotonin levels cause dementia.  We constantly see that when article such as “Cannabis users have lower IQs” and “Teens who use cannabis less likely to succeed in life”, and other such nonsense.

I am happy to present this good quality example from Johns Hopkins by the simple phrase: “Previous studies from Johns Hopkins and other centers have shown that people with Alzheimer’s disease and severe cognitive decline have severe loss of serotonin neurons, but the studies did not show whether those reductions were a cause or effect of the disease. Results of the new study of people with very early signs of memory decline, the researchers say, suggest that lower serotonin transporters may be drivers of the disease rather than a byproduct.”

True, they may believe that the reductions are causal, based on other studies, but they do NOT jump to conclusions like so many biased cannabis reports that strike sour notes with me.   I wish more researchers were wiser and more forthcoming when finding correlations, when causality has not been established, instead of foisting propaganda and lies.

Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia.

The DEA must be upset.  Clearly, they ignore all the scientific evidence and pursue their own job-preserving ways, while they ruin people’s lives and stifle research.  And, Congress knows this (or are complete idiots) but has their lips firmly on Big Parma’s butt cheeks.  (Sigh)  When will we ever emerge from the dark ages?
